Nonsymmorphic materials, which possess special symmetry operations (screw rotation, glide mirror), have been theoretically reexamined in recent years for possible novel quantum phases or electronic functions derived from the symmetry requirements. Here, the authors demonstrate that in the typical nonsymmorphic material IrO2, the type of charge carrier (electron or hole) is strongly dependent on the crystal orientation and capable of being switched by a magnetic field. This remarkable effect is seen in electrical transport measurements on various thin films supported by simple tight-binding and band structure calculations.
